Abstract: 1,094,085. Automatic temperature control. INTERNATIONAL STANDARD ELECTRIC CORPORATION. June 17, 1966 [June 18, 1965], No. 27105/66. Heading G3R. A combined space heating and cooling system comprises a control unit T situated in the space and a remotely situated heating and cooling unit HC for the space, the electrical connection between the unit T and the unit HC comprising two conductors L1, L2 only, by means of which the heating or cooling means H and C may be selectively controlled from the unit T in accordance with variations from a set temperature in the temperature of the space. The control unit T includes two selector switches SW1, SW2 and a temperature sensing device TS the contacts CS of which open and close in accordance with the value of the sensed temperature of the space. The desired space temperature is settable by a pointer DS of the device. The unit HC includes the heating means H, colling means C and a fan F together with two, slow to release, relays RL1, RL2. The unit also comprises a thermocouple device TC responsive to the air circulating over the heating and cooling means HC. With the selector switches SW1, SW2 in the positions shown both relays RL1, RL2 are energized by a transformer TX over the conductors L1, L2 thus energizing the fan F continuously to circulate air in the space. Movement of the switches SW1, SW2 to the "HEAT" and "AUTO" positions respectively causes relay RL2 only to be energized whereupon the heating means H is energized or de-energized according to the position of contacts CS in the temperature sensing device TS, the fan F at the same time causing circulating heated air in the space in dependence upon the condition of the thermocouple device TC. Selection of the cooling means C is effected by placing the switches SW1, SW2 in the "COOL" and "AUTO" positions respectively. Energization of relay RL1 then takes place to energize both the cooling means C and the fan F in dependence upon the position of the contacts CS. When the cooling operation is selected the energization of the relay RL1 is effected by way of a network including resistors R1, R2 and a thyristor SCR.

[Class 146 (iii)] In a magazine pencil similar in general construction to that described in Specification 449,222 there is provided an automatic locking device operative only when the knob 10 has been partially depressed and subsequently released which acts between the clamping sleeve 4 and the tube 2 to prevent the return of the guide tube 2, whereby the gripping member 3 remains open, sc that during the last part of the return movement of the point member 8 the lead is not held and remains in an inoperative position above the entrance tc the channel 9. The clamping sleeve 4 secured to the casing 1 is provided with two locking members 14 having projections 15 which engage notches 16 in the tube 2 when the latter is advanced a distance h by advancing the knob 10 an amount d + h. In this position the clamping sleeve 4 and tube 2 are locked relatively together with the gripping member open. When the knob 10 is advanced an amount d + h the tube 2 is advanced an amount H causing a ring 17 carried loosely thereon to pass between the projections 15 thus allowing notches 16 on the release of the knob 10 to pass between them, consequently permitting the gripping member to return to its initial position whereby the lead is clamped in the writing position. The Specification as open to inspection under Sect. 91 states that more or less than two locking members 14 may be provided and that the ring 17 may be replaced by other means for opening out the locking members for example telescopic parts. Also, the locking members may be provided on the guide tube and the projections on the clamping ring or means other than projections may be provided to produce the locking action. This subject-matter does not appear in the Specification as accepted.

Abstract: 463,868. Moulding concrete &c. GAUDIN, A. T. Oct. 5, 1935, Nos. 27568, 27569, and 27570. Convention dates, Oct. 6, 1934, Oct. 6, 1934, and Oct. 29, 1934. [Class 87 (ii)] In a machine for making moulded articles in which themould 1, Figs. 1, 2, is pivotally mounted and has a bottom 7 and a cover 17 which can be rigidly interconnected, the material to be moulded being laid on the bottom 7 and the cover 17 then applied and the mould given a half rotation and the bottom 7 and the cover 17 displaced relatively thereto to free the moulded article P, the mould 1 is held stationary while the bottom and cover are lowered to free the moulded article P. In one form, the mould 1 is carried on journals 4 and from it extend four rods 2 on which slides a plate 8 carrying through rods 9 the bottom 7. To the plate 8 are pivoted stirrups 13 which engage with cover 17 and hold it in position during reversal, after which pressure is applied to plate 8 and the bottom 7 pushes out the moulded article. The stirrups 13 during the downward movement bear on flanges 11 which force them apart to release the cover 17. With hollow concrete &c. blocks having thin walls the several elements of the mould are successively removed from the moulded block. Cores 5 are carried immovably by bars 6 secured to guides which carry the journals 4 and the mould 1 has two slide bars which permit it to be displaced vertically to a limited extent relatively to the fixed cores 5 and journals 4 to allow the block P to be freed from the cores 5 before it is displaced from the mould. Fixed and movable cores may both be used, the movable cores descending to a lesser extent than the mould so that the block is freed therefrom before it is ejected from the mould. In a modification, Fig. 13, cross-bars 34 are secured to plate 8 and to them are hinged the stirrups 36 which engage and hold the cover 17. The moulded article is ejected by operating a lever 25 which is attached to and rotates a shaft 38 and causes through linkages 24, 28 the descent of two members 26 which are connected by cross-bars 32 and slide on vertical tubes 27. Springs 29 secured to members 26 engage cross-bar 34 and cause descent of plate 8 and ejection of the article. Projecting plates 40 fixed on the mould 1 engage during the descent the stirrups 36 and free the cover 17 which with the article thereon rests on cross-bars carried by the bars 82. The springs 29 are lifted clear of the bar 34 by cams 35 which are attached to the bar 34. The machine is supported by two rigid frames 18, 19 connected by girders 20, 21, the frame 19 being movable along the girders to lengthen or shorten the machine to suit the moulds used. A vibrator may be fixed on a plate which is welded to the bars 6 which carry the cores 5.

Title: A process for the production of oxygen-containing organic compounds
IPC: C07C45/50
Filed: 1949-10-27
Abstract: A modification of the process described in the parent Specification for the conversion of hydrocarbons having at least one olefinic double bond into oxygen-containing derivatives, such as aldehydes and alcohols, by the action of a gas containing carbon monoxide and hydrogen in the presence of a filling mass provided with cobalt or a cobalt compound and packed in the reaction space, in which a gas-containing carbon monoxide and hydrogen is first passed through a mass containing cobalt or a cobalt compound in a preliminary oven, under conditions which promote the formation of volatile cobalt compounds containing carbon monoxide and hydrogen, wherein the pressure used in the preliminary area is appreciably lower than the pressure to be used in the oxo reaction and does not exceed 75 atmos. The gas may contain hydrocarbons including the olefinic reactant. The low pressure prevents heating due to a preliminary oxo reaction and a catalyst of constant composition is obtained.  Thus, when the olefines are present a solution of catalyst is obtained which is stable if air is excluded and if under adequate carbon monoxide tension, e.g. 1-3 atmos. and at 50 DEG  C. at least 1 atmos. Temperatures of operation indicated are 50-90 DEG  C., especially 60-80 DEG  C., and particularly about 70 DEG  C.  The pressure should ensure a partial pressure of carbon monoxide of more than 10 atmos., e.g. 20-50 atmos.  With water gas the pressure should be at least 25 atmos.  Products leaving the oven are cooled and stored.  The conventional decobalting zone of the oxo-synthesis may be used intermittently as the preliminary oven.  In an example an apparatus used alternatively for decobalting and catalyst preparation contains pumice on which 30 per cent weight of cobalt is deposited and is fed with water gas at 70 DEG  C., together with a C6-C8 olefine fraction, the pressure being approx. 25 atmos. and the product after cooling is passed to storage at 1-5 atmos.  The initial cobalt content of the solution is 3 per cent approx. and when it drops to less than 0.5 per cent the process is stopped and the oven used for decobalting.
